Sunpentown Orca Ultrasonic Humidifier Model SU-1441
Although some users have had reliability issues with this model, the Sunpentown Orca humidifier provides solid basic performance while having the cute design of an orca whale. This shape does provide some restrictions as the mist nozzle is not adjustable. This can make it difficult to aim the mist in the desired direction when putting the humidifier on a surface such as a narrow shelf.
Regardless, this ultrasonic cool mist humidifier would work well for a nursery or child's room, with eight to ten hours of mist per tank for rooms up to 450 square feet, and an automatic shutoff feature with no audible alarm (so as to not wake anyone up). A built-in carry handle makes transporting the humidifier easy and non-slip feet ensure it won't slide off a shelf or table.
